Can the computer detect the cylinder pressure?

This problem can't be detected by computer, because the cylinder depression belongs to mechanical work, and the computer can't detect it. I suggest you check it with a cylinder pressure gauge.

Extended data:

The detection method of cylinder pressure is carried out according to the following steps. Step 1: Install the cylinder pressure gauge on the engine.

The second part: warm the car first, let the engine run to normal temperature, and keep the temperature of coolant between 85-95 degrees.

Step 3: Remove all spark plugs or fuel injectors on the vehicle and ground the high voltage line.

Step 4: Step on the gas pedal and let the gas pedal fully open.

Step 5: Screw the threaded pipe joint on the spark plug hole. The conical rubber joint of the cylinder pressure gauge can also be pressed into the spark plug hole of the cylinder to be tested.

Step 6: Start the starter for about two seconds. After the pointer is determined, read the pressure value, and then press the check valve (check valve) button to exhaust and decompress, so that the pointer returns.

In this method, it should be noted that the number of measurements per cylinder is not less than two times, and the average value is the best.

In addition, during the second measurement, a little oil can be injected from the spark plug hole, and then the cylinder pressure can be measured. The amount of oil injected is 20~30ML.

If the cylinder compression pressure is the same as before fuel injection, the valve leakage can be judged.
